Answer:
(i) [-1, 2]
(ii) [2, 4)
Step-by-step explanation:
(i) Both -1 and -2 is included in the set of real numbers. So both the numbers are inside a square bracket.
(ii) 2 is included in the set of real numbers, but 4 is excluded. Therefore, 2 is inside a square bracket whereas 4 is having a curved bracket.
Intervals are used to show the starting and ending points in a Real number Set. The curved bracket shows the number is not included, and a square bracket shows it included the number in the set.
